Kutheni abantu abaninzi bethanda ukusebenzisa izibane ze-LED endaweni yezibane ze-incandescent?

Nalu olunye uthelekiso, mhlawumbi lunokusinceda sifumane impendulo.

Umahluko wokuqala phakathi kwezibane ze-incandescent kunye nezibane ze-LED ngumgaqo wokukhanyisa ukukhanya.Isibane se-incandescent sikwabizwa ngokuba yibhalbhu yombane.Umgaqo wayo wokusebenza kukuba ukushisa kuveliswa xa i-current idlula kwi-filament.I-spiral filament iqokelela ubushushu ngokuqhubekayo, isenza ubushushu bomsinga bube ngaphezu kwama-2000 degrees celcius.Xa i-filament ikwimo ekhanyayo, ibonakala ngathi yintsimbi ebomvu.Inokukhupha ukukhanya kanye njengokuba kukhanya.

Ukuphakama kweqondo lokushisa kwe-filament, ukukhanya okukhanyayo, ngoko kubizwa ngokuba isibane se-incandescent.Xa izibane ze-incandescent zikhupha ukukhanya, isixa esikhulu samandla ombane siya kuguqulwa sibe ngamandla obushushu, kwaye kuphela indawo encinci kakhulu enokuguqulwa ibe amandla okukhanya aluncedo.

Izibane ze-LED zikwabizwa ngokuba yi-light-emitting diodes, ezizizixhobo eziqinileyo ze-semiconductor ezinokuguqula ngokuthe ngqo umbane ekukhanyeni.Intliziyo ye-LED yi-chip ye-semiconductor, enye isiphelo se-chip ifakwe kwi-bracket, enye isiphelo sisibonda esibi, kwaye esinye isiphelo sidibaniswe kwipali echanekileyo yonikezelo lwamandla, ukuze yonke i-chip ifakwe. nge epoxy resin.

I-wafer ye-semiconductor yenziwe ngamacandelo amathathu, enye inxalenye yi-P-type semiconductor, apho imingxuma ilawula, enye isiphelo yi-N-type semiconductor, apha ubukhulu becala ii-electron, kwaye umbindi udla ngokuba ngumthombo we-quantum kunye no-1 ukuya ku-5. imijikelo.Xa i-current isebenza kwi-chip ngocingo, ii-electron kunye nemingxuma ziya kutyhalwa kwiqula le-quantum.Kwimithombo ye-quantum, i-electron kunye nemingxuma iphinda idibanise kwaye ikhuphe amandla ngendlela yeefotoni.Lo ngumgaqo wokukhutshwa kokukhanya kwe-LED.

Umahluko wesibini ulele kwimitha yobushushu eveliswa zezi zimbini.Ukushisa kwesibane se-incandescent kunokuvakala ngexesha elifutshane.Okukhona amandla amakhulu, kokukhona ubushushu.Inxalenye yokuguqulwa kwamandla ombane kukukhanya kunye nenxalenye yobushushu.Abantu banokubuva ngokucacileyo ubushushu obukhutshwa sisibane se-incandescent xa besondele kakhulu..

Amandla ombane e-LED aguqulwa abe ngamandla okukhanya, kwaye imitha yobushushu eveliswayo incinci kakhulu.Uninzi lwesakhono luguqulwa ngokuthe ngqo lube ngamandla okukhanya.Ngaphezu koko, amandla ezibane eziqhelekileyo aphantsi.Idityaniswe nesakhiwo sokuchitha ubushushu, ukukhanya kwemitha yobushushu bemithombo yokukhanya ebandayo ye-LED ingcono kunezibane ze-incandescent.

Umahluko wesithathu kukuba izibane ezikhutshwa zezi zimbini zahlukile.Ukukhanya okukhutshwa sisibane se-incandescent kukukhanya kombala ogcweleyo, kodwa umlinganiselo wokubunjwa kwezibane zemibala eyahlukeneyo umiselwa yinto ekhanyayo kunye nobushushu.Umlinganiselo ongalinganiyo ubangela ukuphoswa kombala wokukhanya, ngoko umbala wento phantsi kwesibane se-incandescent awunyani ngokwaneleyo.

I-LED ngumthombo wokukhanya okuluhlaza.Isibane se-LED siqhutywa yi-DC, akukho stroboscopic, akukho zixhobo ze-infrared kunye ne-ultraviolet, akukho ngcoliseko yemitha, unikezelo lombala oluphezulu kunye nokukhanya okuthe ngqo.

Akunjalo kuphela, ukukhanya kwe-LED kunokusebenza kakuhle kwe-dimming, akukho mpazamo ebonakalayo eyenzekayo xa ubushushu bombala buguquka, kwaye umthombo wokukhanya obandayo unesizukulwana sokushisa esiphantsi kwaye unokuchukumiseka ngokukhuselekileyo.Inokubonelela ngendawo yokukhanya etofotofo kunye nelungileyo Ngumthombo wokukhanya osempilweni okhusela amehlo kwaye uyahambelana nokusingqongileyo ukuhlangabezana neemfuno zempilo yabantu.
